T all whom it may conceive:

Be it known that I, WILLIAM WILLINK. e citizen of the United S siding etBrooklyn, in the county Ano. T. tetes, re of Kings and State of NewYork, have invented certain new and useful Improvements coal-Retorts,specification.

in Cherof which the following is a My invention relzites to charcoalretorts, end has tor its object the production of means for cerbonizingwood or the l ing devices and mechanism of spe struction endpnrticulsrerrengen lowering and raising the retort and ing it into and out of theis believed that Vthe ike hevciof conient, for for mow funn lice,whereby it recess is more expeditiously and conveniently conducted andthe product thereof tained from any with which l am superior toapparatus for like familier.

that obpurpose I accomplish the stated object by foshion ing andassociating the parts es illustra-ted in the accompenying drawings, ofwhi Fiffure lengtiwise of the furnace and the its horizontal attitudewithin the 1 represents e vertical section retort in furnace.

The ,furnace has, esordinarily constructed, the sub-floor srnolte .flue 2 Aprovided with ademper 'The outside vertical freine bars or well-retaining bars srcreferred to by number 4, and the horizontal cross-beams constituting thetop of the freine are designated by number 5. The flanged track Dennis 6'are secured beneath the cross-beams 5 lengthwise of the furnace. lt isupon the lower flanges of the track beams tlm-t the carriages supportingthe retort are movable es hereafter explained.

Through the middle of the top ol' the furnace is s. longitudinal slot 7,liest shown in liigs. 4 and 5, and following the edges of the slot onthe outside of the too of the furnace are the channel irons 8, filledwith sand 9. Into the sand are inserted the edges of the sides of thegrooved cop piece 10 which effectuslly closes the slot against theescape of smoke from the interior the furnace. To more positively closethe slot, l provide, in addition to the csp 1piece 10, e sheet metalplug 3.1 which lies the forni in eross-section illustie'wfA in Fig. 5,and extends the length of the ccp piece, to which it may or may not heattached. l imiy use the oep piece alone lug is omitted in Fig. l.. inFig. 5 it will ie observed that the cross-beams 12 which support the'top of the furnace stop et the slot 7, end thet their ends nresupported by the iicsins 13 running lengthwise under them.

llie retort lli is supported at the rear by the singleverticnl rod 1.5pivotelly mirinccted with the heck of the retort. Rod 15 posses upwardlythrough the slot 7. At the front, rods 16 mid 17, :uid 'those rods donot cuter the furnace hut extend upwardly in front of it :is shown inFig. l-.

begins is hij.

At the point where ilily front carriage 19 is attached to the lmrs 1F,there are also secured to tliehlntrs suitable luuigers 23, the purposeol:` which is to support the parallel,

transverse short beams beams 24- are joined together near their ends bythe blocks 25, and the screw rods lo and 17 pass upwardly through theblocks 25 and through the Worin wheels 26, `which are provided withinternal threads that engage the threads of the rods. rlhe Worin Wheelsrest on the blocks 25, and they mesh with worms 27 on thev transverseshaft 2S. lt is believed to be made apparent that if the shaft 2S beturned by means of a wheel 2E) oper.

.from Which position no part of the operation can displace them. Thelowered position ol' the retort is indicated by broken lines in Fig. 2.

ln the construction ef my invention, the irons Which 1 have termed thetrack beams are extended before the furnace and suitably supported.Thus, the carriages 19 and 20 permit the retorttoy be drawn from thefurnace in order to discharge it, and it is convenient but notabsolutely necessary to have a pulley 31 o erated by cable or chain 32,to turn the iv ieels 22 ofthe carriage IQ-and cause it to travel eitherWay upon the track. It will be observed that the Wheels 22 are inclinedwith respect to the ulley 31, but, as best shown in Fig'. 7, the sliaftof the pulley may be provided With a universal joint and thereby operatethe gears 33 arranged for driving the wheel or wheels 22. Any desiredcontrivance may be substituted for the parts, just described and whichconstitute no essential part of my invention.

A hinged door 34 closes the front opening or mouth of the retort, andthe door is secured to the annular mouth-frame of the retort by thehinged clamp 35. It is also desirable that the retort when introducedinto the furnace shall be' effectively held there against displacement,particularly in the direction which would cause it to move out ol' thefurnace. To suitably hold retort in the furnace, l provide theturnbutton 36 on the flange 37 of the mouth-frame of the furnace, andthe turnbutton engages the llaiigcih of the mouth-frame of the retort.Again considLing Fig. 1, it will be noted that the door 34 which isshown in section has l'oi'ined in its upper portion a curved channel 3),which is connected with a dis- .charge pipe 40,4 and by Way thereof thegases emitted by the charring Wood find veut.

ln the operation of my invention, after the rctortdias been charged inthe customary substantially as described.

24. The short manner, it is pushed or propelled into the fur lt \\'illthen take the position shown'v iu Fig. l with the vertical suspensionrod l5 near the rear: wall of' the furnace. 'lo reach that position andto again inove l'roni it the rod must clear y pass along the slot 7, andthe slot must be closed by the cap piece 1t); and plug 1'1 before thefiring begins. 'hen the )recess has been completed, and it is desired tomove the ret-ort out of the furnacel to cool, discharge and recharge it,Without at the same time cooling the furnace and losing unich heat, thecap piece must necessarily be removed until the rod passes out of theslot 7, whereupon the cap piece may be replaced and the damperl 3 closedto retain the neat within the furnace for another charring operation.The retort having passed out of the furnace into the positionillustrated in Fig. 2, the Worin Wheels 26 :ire rota-ted by turning theshaft 2S by means of the pulleir 29, and the retort is lowered until ittakes the attitude indicated by the broken lines. The door 34 being thenunfastened and opened, the contents of th retort are discharge Havingnow described my invention and explained the' mode of its operation,what I claim is-. f
